You're right of course, I just wanted to post like a jerk JUST LIKE YOU. Why? Because:
Your people skills are obviously superior.
You are never wrong.
If you were wrong, you would want someone to be as sarcastic as possible pointing out your mistake instead of pretending to be human and merely correcting you.
I made one 14" monitor run pretty darn hot, so hot that it began to smell like melting plastic. I suspect I was running it out of spec. I had just changed my X config to run at a higher resolution, so changing it back "fixed" the problem until I was able to find one of the standard configs that worked at all resolutions.
I have 2 celeron 300A systems clocked at 464. I have 3 suggestions.
First, go get a celeron especially if you're a bit short on cash. The bang for the buck is waaay up there.
Second, make sure you get a good motherboard. I use ABIT motherboards almost exclusively because they make good overclocking boards and they are very easy to set up. I'm sure there are other, more stable boards out there but ABIT works for me. There is also a dual celeron processor capable ABIT board out there, I think it's the BP6.
Third, visit some web sites that offer celeron/motherboard/ram packages and see what you can get. There are places that will sell you a celeron 366 guaranteed to run at 550mhz for right around the price of a "real" celeron 466. Check out http://www.computernerd.com for examples of what I'm talking about. They're not the only site out there though.
If you get a dual processor mobo and eventuallly get 2 of those celeron 366's clocked at 550 each, you would be running a pretty darn fast linux box:) You didn't mention whether your 3D gaming is under windows or linux, and a dual processor setup is pretty much useless for win9x gaming, at least until the SMP win2K release is stable.
It would have to be one hell of an impact to eject life-bearing chunks from earth to another planet... The delta-V would be enormous, and the heat released (imagine just the propellent required to get from the earth to the moon released in a split-second impact...) seems enough to kill anything living that happens to be riding along on.
I'm not saying it couldn't happen, but the mechanics involved don't point towards a friendly ride for even bacteria that could theoretically survive intense heat/pressure plus the cold vacuum of space.
IR transmissivity is dramatically reduced by water in the air, both visible (fog) and invisible (absolute humidity). Smoke and dust can affect IR visibility especially if the cause of the smoke or dust is associated with thermal activity (an explosion) but in general dust and smoke particles do not block or distort IR energy nearly as much as water.
The military uses absolute humidity to predict IR visibility ranges for various sensors because it's one of the biggest factors affecting IR transmissivity.
Of course, how much the sensor is affected depends on the particular wavelength that sensor is sensitive to... Some of the best IR bands require active cooling to operate properly, but once the sensor is cooled they can provide incredible image resolution, temperature discrimination, and can "see" through dust, smoke, and some gasses without any problems. Water vapor is still a huge problem though.
Short answer - don't expect an IR sensor to work in the rain or through fog, but they should work ok (probably lose some contrast and range) through dust and smoke.
One big problem will be boresight alignments. Unless the sensor is placed on the roof near where the windshield meets it, there will usually be at least 3 ft difference in the line of sight of the driver and the sensor. This means that the image will not always line up with what the driver sees with his own eyes. I wonder how they plan on dealing with the double images drivers will be seeing, or if they're not going to have it as a see-thru hud, rather a small opaque display at the base of the windscreen. Either way, matching up the display with the real world will take some of the driver's attention away from driving, and lots of drivers have enough problems just keeping on the road let alone looking at some camera view too.
I agree that it could be a potential hazard. Military pilots require several training flights and a few hours of academics before they use their FLIR systems simply because no matter how good the system is, they aren't perfect and can "lie" to you. For example, a rather hot object might show up as a large blob on an IR screen even though it might only be something small. In addition, the boresights of the FLIR camera will never be spot-on to the driver's line of sight through their eyes, so the image displayed by the camera will not always line up with the real world.
I honestly think there's going to be a lawsuit concerning these thing because someone is going to run into someone or something because they followed the displayed image instead of using their own eyes, or they're going to get confused when their eyes disagree with the displayed HUD image and they freeze up in confusion and cause an accident.
Highly skilled military pilots with extremely good reflexes and eyesight have been misled into accidents and collisions because of similiar equipment, so I fully expect there to be accidents when the average driver starts using them.
FWIW, I'm a USAF F-15E pilot and have used FLIR systems for 3 years. Even with the latest military technology, these artificial vision systems will sometimes mislead you and they can cause accidents if the driver/pilot is not aware or alert enough to make sense of the information.
I think the web itself has replaced the BBS concept, neatly filling in and replacing all the features most old BBS systems had.
Instead of logging into a BBS and seeing who's online, I dial my isp and ICQ wakes up showing me if any of my friends are online. Instead of checking my favorite discussion forums, I go through my browser favorites hitting 5-6 pages and web BBS'. I also get to check stock quotes, something I never could on the BBS' I used to frequent.
Email is checked while web pages are downloading since I only have a 56k modem, and I also pass along pointers to interesting web sites via email. A quick check on my gaming email list and one last sweep of ICQ, and I'm off the online gaming arenas. Instead of playing poker in the chat room, I fly a virtual P-51 Mustang or B-17, and do my chatting while shooting at other people online. Unlike many MUD's and other early online games however, the games I play are against real people not AI routines, so it's all about interacting with real people. Some get chat windows, some get virtual bullets...
Anyhow, my point is that for me, I've found that sense of community with the web at large replacing and expanding on the old BBS features. The BBS sysadmin is replaced by thousands of users, webmasters, content providers, and application programmers all working with a common set of protocols. I agree, AOL is probably one of the very few places that provide most of the typical BBS features in one place, but for a user willing to experiment and "get out there" and search a bit (like browsing BBS file areas eh?), all the tools necessary for the community are easily available. I don't think I'd go back if I could.
Based on some of the arbitrary limits in the original x86 based pc's like 640k limit, I sorta consider much of the original PC design to be an "Evil Hack" in the spirit of Dr. Evil from the Austin Powers movies. Nobody could possibly want more than 640K memory eh? Bah. Same thing with 2-digit dates. Laziness and bit-picking to save one penny per machine, and now people are getting rich selling $90 RTC cards to people who don't even know if they need one.
Unless he was deliberately trolling for flames, I think that Eric Corley aka Emmanuel Goldstein has no idea how expensive some of his ideas are. For example, near the end of the interview he claims that there should be no problem with people hacking into the Pentagon's web site (or any government web site) simply because there is no classified information on those sites. He completely misses the point that hundreds of thousands of people utilize those resources in their daily work, and a hacker-turned-criminal (to use his definitions) could effectively waste thousands of man-hours while important information was recovered from backups. On a personal note, if a hacker was to destroy the information kept on the networked computers in my office, it could potentially take up to 2 weeks to recover and reconstruct the information because our data changes daily making reliable and complete backups extremely difficult. For my time alone, that's over $2000 spent by the American taxpayer, and my shop directly controls how over 200 others spend their time at work.
Fortunately I'm behind a firewall that makes doing even legitimate work very difficult, plus my shop is protected by relative anonymity amongst hundreds of computers on the LAN...
In addition, while there is no classified information accessable from the internet, there are often documents that could potentially cause the government to waste millions of dollars or even potentially risk the lives of servicemen and women if those documents were destroyed, altered, or misused. I even have an example. Safety reports are supposed to be official use only for many reasons, but there is one huge time/money wasting reason to keep some information for official use only. In order to ensure that people involved in accidents fully cooperate with safety investigators (to prevent future accidents), all information gathered by the safety investigation team is privledged information much like anything you tell a lawyer is privledged. There have been cases where information in those documents have led to multi-million dollar lawsuits that never should have happened, simply because the document was given to the wrong person.
This kind of abuse directly wastes taxpayer dollars, and has the potential to cause loss of life because if it keeps happening, people will not cooperate with safety investigations in the spirit of the 5th amendment of the Constitution.
These are only a couple of examples that point out the childishness of Corley's statements. He suggests that the ability to literally throw away millions of dollars in lawsuits and wasted work hours is a desired and legitimate end state simply to satisfy his and other's curiosity. I'm 100% in favor of "hacking" as a way to solve everyday problems with unconventional solutions, but I fail to understand why he says hacking private, corporate, or government sites is "ok" simply because there is no classified information on that site. In some cases, simple unauthorized distribution of unclassified information can be truly damaging and dangerous. Doing so in some misguided attempt to further a hacker spirit is not "ok", it's unethical and in many cases criminal.
This is of course my opinion, not that of my employer. Direct flames to/dev/null or email me directly if you must.
Was looking forward to reading stuff from the cDc web site after briefly browsing it from work, but from home my isp's DNS server returns unknown host for www.cultdeadcow.com. I asked a friend to look up the ip address for me, and his isp also returned unknown host.
2 possibilities? First the site is down. Second, some ISP's delete cDc from their DNS tables? Had no trouble finding the site from work even through their firewall (.mil) but I didn't write down the ip addy (stupid me).
Any help would be appreciated. Before I left the site I saw lots of interesting stuff I wanted to spend some time reading (Thanks cDc)
I have a windows machine at 16 meg ram that is barely suitable for it's job, while my linux box with enlightment with 128 meg ram is running just fine. A relative measure of system resource effiencicy might help those who are resource limited.
With 128 meg ram (bought when 128 meg PC-100 SDRAM was ~$99) enlightment is very suitable.
What we need to make Linux mainstream in terms of graphical user interface, is ALL configuration options available via a standard interface. Whether this is available from a "standard" distribution (aka RedHat or whatever) or a default linux X-config interface, is moot. The root of the problem lies in the fact that there are few standard configuration frontends that can configure the entire OS with a single interface.
Microsoft has gone almost as far as the redhat configuration tool, but there still some distance to go. A single standard interface to all configurations is a holy grail we should be reaching for. I'm just a USER so my opinion can be discounted appropriately, but users worldwide are looking for a single button they can click on that will let them set up or configure any feature or service regardless of window manager or OS GUI interface.
That said, I'm limited to make config because I'm too stupid to understand the error messages printed after the first (and only) time I ever use make menuconfig on any given system.
